Abstract
Abstract The relevant data on the quality of service at different positions within a coverage area which is to be monitored of a mobile radio installation are ascertained by test mobile remote units (16) that are preferably mounted on vehicles which travel regularly on random routes (20) in the area. The test mobile remote units (16) acquire and store the call identification and connection parameters and the time and position data. Evaluation is effected via a test control unit (17), which is connected to a mobile switching center (15).
